The goal is to ensure quality for a period of time after you buy it. That can be several days to several weeks, depending on the item. For instance, milk, assuming proper refrigeration, should last five to seven days past its sell-by date before turning sour.
An autoencoder is a neural network that is trained in an unsupervised fashion. The goal of an autoencoder is to find a more compact representation of the data by learning an encoder, which transforms the data to their corresponding compact representation, and a decoder, which reconstructs the original data.
An assembler is a program that takes basic computer instruction s and converts them into a pattern of bit s that the computer's processor can use to perform its basic operations.Some people call these instructions assembler language and others use the term assembly language. This sequence of assembler instructions, known as the source code or source program, is then specified to the assembler program when that program is started.
